please any suggestions ??? I'm getting a bit worried

I'm almost 15 weeks & I can't eat anything!!! Anything I look at makes me sick as soon as I try to eat it I get sick to my stomach or puke, I'm on the morning sickness meds, but since the second trimester started I can't eat anything help!! I know it's bad for the baby! I'm getting worried I'm not getting enough even though I'm trying,
